GOMBING MACHINE.

Applicationfiled September 26, 1922.

To all whom it may concern:

Be 1t known that I, JAMEs J oLLr, a British sub ect, resldlng at Deane.Bolton, county of Lancaster, England, have invented certain new anduseful Improvements in Cornbing Machines, of which the following is aspecification.

This invention relates to combing machines of the Heilmann=llasmith typein which an oscillating movement is imparted to the nippers and topcombsto cause them to approach to and recedefrom the detaching rollers.

In the Nasmith coniber, the nip-per, the feed roller and the top combare all mounted in a single oscillating frame. about which ito'scillatesis below the cylinder, the movements of the several partsbeing obtained by connections to fixed parts. In this construction thenipper oscillates in a path eccentric to the cylinder and is furtheraway from the needles of the cylinder at the commencement of theoscillation than at the finish and consequently the cotton held by thenipper is not equally combed by all the rows of needles of the cylinder.

The object of this invention is to maintain the nippers when closed asthey move or rock to and fro, a constant distance from the needles ofthe cylinder and to get the cotton held by the nipper s down to the pathof the needles of the cylinder in advance of each revolution.

According to the invention the nipper frame is carried on a bearingframe oscillating about the axis of the cylinder and in a pathconcentric with the cylinder.

The invention will be fully described with reference to the accompanyingdrawings in which a oomber head embodying the invention is illustrated.

Fig. 1' is an end elevation showing; the

nipper in: its advancedposition towards the detaching roller's,'thenipper jaw raised and Fig. 2 is a transverse section showing the partsin the same position as Fig. 1.

Fig. 3 is a transverse sectionshowing the parts in position. duringcombing operation furthest from the detaching rollers.

Fig. 4 is a detail of the feed roller ratchet.

Fig. 5 is an elevation looking from back in direction. of arrow Fig. 1..

Fig. 6 is a perspective view of the hearing The centre i feria1 No.590,719.

Fig. 7 is a perspective View of one end of the nipper frame C.

The detaching rollers A are -1nounted to operate in the ordinary way andthe cylinder A" is of ordinary or known construc tion mounted on a haft;c carriedin been lngs a on the standard or frame of the machine. v

An oscillating bearing frame Bis mounted on the bearings a,concentriewi-th the cylinder shaft aandisfree to oscillate around thecylinder shaft a.- The bearing frame B is provided with bearings 12 atboth ends to support and carry the nipper frame G.

The nipper frame 0 is constructed with a longitudinal plate 0 with shortupstanding portions formed with a pivot- 0' at each end bywhich it ismounted in the bearings b of the bearing frame in which it is capable ofrocking for alimited distance to allow the nipper when closed tooscillate at a con stant distance from the needles. For the purpose ofadjusting the position of the nipper frame C in relation to the bearingframein either direction set screws 6 are screwed into lugsorprojections thereomthe back screw to adjust the height of the cushionplate D relative to the steel detaching roller A and the front screw toadjust the descent ofthe nipper knife and plate D to the desireddistance from the cylinder needles. It is provided at both ends withupwardly projecting lugs or cheeks c to carry the top nipper jaw E, thetop comb F and the feed roller Gr, all of the members being thus carriedon the nipper frame C which is itself pivotally carried 'on bearingframe B.

The cushion plate D forming the bottom jaw of the nipper maybe formed bythe I arms or levers 71. on the roc-kingsh-a'ft K. The

studs 6 are substantially the same distance from the plane of plate 0'as the pivots- 0..

The arms 6 of the nipper jaw or knife extend rearwards beyond the nipperframe and are attached to springs e which are anchored to a fixed partof the frame.

The arms f carrying the top comb F are pivoted to the upper end of thelugs or cheeks c of the nipple frame C and the feed roller arms 9 arealso pivoted on adjustable studs carried by the lugs or cheeks 0 thefeed roller being rotated intermittently by a ratchet and pawl as thenipper frame C and nipper is moved forward. The rearward enlarged endsof the feed roll arms are connected by adjustable springs to the upperparts of the checks a so that the feed roll is thereby spring-pressedagainst the cushion plate D.

R A stationary cam or inclined surface M is adjustably secured to themachine frame adjacent each top comb arm 7 to support the bowls m onsaid arms and thereby control and operate the top comb, giving thedesired lift and fall in the familiar manner. Similarly a stationary camN, adjustably supported on a fixed cross-bar of the machine at about thecenter of the combing head, is engaged by the bowl n centrally journaledon the cross-rod which connects the two nipper arms 6. This cam causesthe nipper knife E to open at the desired time as will be understood.

The whole mechanism receives its oscillating or rocking movement from arocking shaft K (operated by cams not shown) through the arms or levers71. and connecting rods H pivoted to the nipper frame C on the studs(2'.

In operation as the bearing frame B oscillates and moves forward towardsthe detaching rollers A it carries with it the nippers D, E, the topcomb F and the feed roller G. Towards the end of the forward movementthe runner a contacts with the fixed cam plate N and causes the topnipper aw to move away from the cushion plate allowing the cushion plateto rise oscillating on the bearing 0 to the extent permitted by the rearset screw and at the same time opening the nippers and releasing thefibre therefrom. The runners 771. of the top comb F traverse along theincline or cam plate M and allow the top comb to fall into position andthe ratchet of the feed roller G is advanced as the g is held by the pin9 As the hearing frame B oscillates and moves away from the detachingrollers A, the nipper E and top comb move back with it, the runner a 011the nipper arm leaves the cam plate N and the spring causes the topnipper jaw to close on the cushion plate and hold the cotton and at thesame time forces the nipper downwards closer to the needles of thecylinder to the position determined by the front set screw 0 and therunners on of the top comb F traverse the incline cam plate M and liftthe top comb F.
